' ,'1-hus rim m'em bers are stronglj supported by thehub, butsuifieient resiliency; is obtained to permit the wheel to withstandsevere i shocks and strains without damage. 1 In the construction shown, the'discs 89,-are-= provided with {bosses- 10 at intervals .around 1 the 'wheel; for the ettachment of-anti-skid de-f vices, bnt'thes e ere'n'ot essential; 2 11? indicates an intermediate r m. member; whichis disposed betweenthe marginal rim,- m'e'mbers 6"'7. end-"is spaeed apart jromj them' -as shown in Fig.1. :The intermediate rim member 11' is corineetedgwith; the map; naL i JmQmbQ and heii r e e; rm'm ee e e- Qnn c ed to 'e h ze w e entire rim structure efiecti-vly braced; together bye series of trensversel -djsposed; internal ribs or trusses 12, best shownjin Fig; '1. [These ribs are disconnected fromtheiing termediete ortions ofthe discs 859,,but are integre y connected; at their .end; pore-- tions with the merginel rim members 6-7 and with said; discsnt the point of theiri jnnctii re, with said rim r ne nbersg. ancient end Y 80 which also they are integrally. connected,

The intermediate port on of thesefirib s is wider than the end -.portions. thereof soesto, give additional .stren th tittheceirtrzifplixy, tion of the Wheel,.end 'pireferefily their; innermargins are {node convex, as; ;shQwn. --.A1 0 tlieirjend-poi'tions are prpvided with fian es, 13 141 whichfezztend laterally 'et gboth thereof and connect the adjacent nergi'ns of tively, so es'to fljirtherstrengthen the; con-, neetions at vthose points. The outer-(surfaces of' the fie'ng'es 1113-1-14 lie below the o'liter..iir-,

In the wheel illustrated'these pertsj are all cast integral with each other, and 1 combine to produce awheel which'possesses the desirable iqualities hereinbefore mentioned as the objects of my invention. I I111 portant advantages of making the transverse ribs l2'independent 0f the intermediate por- 11b "the-wheel :and connected with the marginal tions of the discs 89 which connect therim members 6-7 with the hub are that the wheel maybe more successfully manufactured by acasting process as the danger of' fracture from shrinkage strains is avo ded and the r'ull resiliency of the discs 8-9 is.

preserved... v g g In the construction shown in F1gs. 3-l,

instead of using the discs.8+9to..connect the rim structure with the hub, I employe series ofnholl'ow spokes-16;"the inner endportions' of which are-connected with: the

hub 5, while their outer end portions arefla'red or curved butwardly at the sides of l rim members 6- as -shown in Fig; 3.

The several spokes 1 Gfare connected-with" each other by =intermed'1ate Fbridging portionslf which merge with the outerjflared portions of the spokes 16, as shown in'Fig: 4:, and also connect with the lateral rim members Gt-'7, so that the rim members are" continuously supportedcircumferenr tially or the wheel. "The rim structure of the Wheel shown in" Figs. 3' 4 is 'in other 7 respects the 'saine a-sthat shown 'HJ'FIgS'.

1-2, the-"seyeral parts being indicated'b the same referenee numerals With'the addition of 'the'exponent'a. In this type; of wheel also the transverse ribs 12 are 'inde pendent of the intermediate portions of the devices; in' this instance the spokes, "which connect the rim membei'swith'the hub.

It willbe understood that my improved wheel may be provided withtlie usual driving gear andbralre'drumwhen used on the rear axle'of a truck, but such parts have nothing to 'do' :with, my resent invention, and as "the manner "in which they are ap-, plied is" well understood by those familiar with thelart; is not believed to be n eces-Q sary toxillustrate 'them. Also the .tire isnot a shown as it maybe-applied to the wheel in any suitable way.
